NARISHIGE NMN-25A Precision Linear Translation Stage

Overview

The NARISHIGE NMN-25A Precision Linear Translation Stage is a compact, manually operated micrometer-driven translation stage engineered for high-reproducibility positioning in optical alignment, micro-manipulation, and laboratory instrumentation applications. Designed and manufactured in Japan under strict quality control standards, the NMN-25A employs a precision-machined aluminum alloy body with hard-anodized sliding surfaces to ensure dimensional stability, corrosion resistance, and long-term mechanical integrity. Its core mechanism utilizes a calibrated micrometer screw with fine-pitch threading, enabling smooth, backlash-minimized linear motion over a 25 mm travel range. Unlike motorized or piezo-based alternatives, this stage delivers deterministic, tactile feedback-controlled positioning—ideal for setups requiring manual iterative adjustment without electrical integration or software dependency. It is commonly deployed in confocal microscopy sample staging, fiber optic coupling alignment, patch-clamp electrode positioning, and calibration fixture assembly where sub-10 µm repeatability and mechanical rigidity are critical.

Key Features

• 25 mm unidirectional linear travel with micrometer-scale resolution (0.01 mm graduation, 0.005 mm estimated interpolation)
• High-strength anodized aluminum alloy construction—lightweight (27.5 g) yet torsionally rigid for vibration-damped operation
• Pre-lubricated, low-friction sliding rails with optimized surface finish to minimize stiction and hysteresis
• Integrated M3 and M4 tapped mounting holes on base and top plate for universal compatibility with NARISHIGE manipulators, optical posts, breadboards, and custom fixtures
• No external power required—fully manual, ESD-safe, and intrinsically compatible with electromagnetic-sensitive environments (e.g., MRI-adjacent labs, electron microscopy suites)
• Compact footprint (52 × 185 × 60 mm) enables integration into space-constrained optical paths or multi-axis stack configurations

Sample Compatibility & Compliance

The NMN-25A is not a sample-holding device per se but serves as a foundational positioning platform for mounting specimens, sensors, probes, or optical components. Its load capacity supports up to 1.5 kg centered load while maintaining specified repeatability—sufficient for most micro-manipulator tips, miniature cameras, laser diodes, or passive optical elements. The stage conforms to general laboratory equipment safety guidelines per IEC 61010-1 and carries CE marking for use within EU-regulated research and industrial settings. While not certified to ISO/IEC 17025 or GLP-specific validation protocols out-of-box, its mechanical traceability, consistent manufacturing tolerances, and documented repeatability make it suitable for inclusion in validated workflows when accompanied by user-performed calibration records (e.g., via dial indicator verification per ASTM E1050 or ISO 230-2).

Software & Data Management

As a purely mechanical translation stage, the NMN-25A operates independently of software control and does not generate digital output. However, its position can be externally tracked using optional accessories such as linear encoders (e.g., Renishaw RESOLUTE™), digital readouts (DROs), or vision-based metrology systems. When integrated into automated platforms (e.g., via third-party motorized conversion kits), positional data may be logged through host controllers compliant with IEEE 1451.2 or OPC UA protocols. For regulated environments requiring audit trails, users may document manual adjustments in electronic lab notebooks (ELNs) adhering to FDA 21 CFR Part 11 requirements—though the stage itself imposes no inherent software dependencies or firmware constraints.

Applications

• Optical alignment of laser sources, collimators, and photodetectors in free-space optics benches
• Coarse-to-fine positioning of micropipettes and microelectrodes in electrophysiology rigs
• Adjustment of specimen height and lateral offset in inverted and upright fluorescence microscopes
• Calibration reference staging for profilometers, interferometers, and coordinate measuring machines (CMMs)
• Modular integration into multi-axis goniometers or XYZ nanopositioning stacks for beam steering or scanning
• Prototyping jigs and test fixtures requiring repeatable, tool-free repositioning during design validation

FAQ

Is the NMN-25A compatible with other NARISHIGE manipulators?
Yes—the stage features standardized M3 and M4 threaded mounting patterns aligned with NARISHIGE’s SR, MO, and MN series manipulators, allowing direct mechanical coupling without adapters.
Does it include a locking mechanism?
No—the NMN-25A relies on inherent friction and micrometer preload for positional hold; for vibration-prone environments, users may apply optional locking screws or integrate external brake clamps.
Can it be used in vacuum environments?
Not recommended for high or ultra-high vacuum (UHV) due to anodized surface outgassing and lubricant presence; however, it is suitable for dry nitrogen-purged or low-vacuum (<10⁻² mbar) enclosures with prior bake-out validation.
What maintenance is required?
Periodic cleaning of rail surfaces with isopropyl alcohol and light reapplication of fluorinated grease (e.g., Dow Corning® Molykote® 321) every 6–12 months under typical lab usage.
Is calibration documentation provided?
NARISHIGE supplies factory-assembled mechanical verification reports upon request; end-user calibration using traceable length standards (e.g., NIST-traceable gauge blocks) is recommended for GxP-critical applications.
